# What does "Full Disk Access couldn't be confirmed" mean?

Storage Studio tried to check whether it has Full Disk Access and couldn't get a clear answer. Rather than assume it's allowed — and then fail halfway through a job — it assumes it **isn't**.

Open **System Settings → Privacy & Security → Full Disk Access** and make sure Storage Studio is switched on. If it already is, switch it off and back on. That removes the doubt.
